To all 1071mm z'i Inlay concern:

Be it known that I, JOHN U. \VILsoN, of Boston, county of Suffolk, State of .\Iassachusetts, have invmited an Improvement in Sig- 5 nill-Transmitters, of which the following description, in connection with the accompanying drawin s, is a specification, like letters on In. Fig. 5 will be seen the several wheels whichl preferably employ in their relative positions, they being arranged herein in two vertical rows to save space on the drawings. In placing the wheels on the shaft wheel l willbe at the end remote from themotor. Then the following wheels will be arranged in succession, 26 2' 2s 29 30 3] 32 33 34: 35 36 37 38 l 39 i0. \Vheels 20 2s 30 32 :n 36 as will be l the tens-transmitting wheels, and wheels 27 29, 31, 33, 35, 37, and 39 will be the units-transmitting wheels. The surface of the selectingcylinder in. this instance contains but Very few studs or projections, they being arranged in rows, and there being one stud or projec tion in each row for the units and one for the tens.

If a number more than 95) is desired, additional wheelssuch as herein shown at 25 would be employed, its contact portions being arranged on its periphery at a different point with relation to the following wheel or wheels, so as not to interfere/I. 6., so that no two contacts will engage the contact-pens at the same time; but, as herein represented, only a small number of contacts can be placed on this wheel. This wheel. 25 has but one contact portion, and hence such numbers as 112, 113, &c., can be transmitted, and for these numbers the signal-selectin cylinder will be pro vided with three studs or projectirms in each row, as best shown in Fig. 4-.

By the signal-transmitter herein described a large number of signals may be transmitted easily with but a single dial and pointer.

By arranging the contact-points of the sigl nal-wheels part on one side and part on the other it will be seen that by a single revolution of the shaft two, or, if desired, three, signal-wheels may successively effect changesin the circuit.

I have herein shown one wheel, as l0, to be used as awheel for a special number, it being herein represented. as formed to transmit number 12].

I claim 1. In a signaltransn1itter, the slgnal-selectl ing cylinder having thereon studs or projec tions arranged in rows, each row comprising two studs differently placed-one for units and one for tens-and a series of contact-pens, combined with a series of circuit-changing wheels, each having contact portions upon but a portion of its periphery, part of said wheels being the units-transmitting wheels and part being tens-transmittin wheels, the co-operating (.=ontact-pens being moved into engagement with the wheels, respectively, by the aforesaid studs or projections, substantially as described.

2. In a signattransmitter, the signal-selecting cylinder, dial and pointer, and a series of contact-pens, combined with a series of circuit-changing wheels, part of which hay'e contact portions upon one half or less of each periphery :for units and another part of which have contact portions upon the opposite half or less of each periphery for ten s, substantially as described.

3. In a signal-traiismitter, the signal-selecting cylinder, dial and pointer, and a series of contact-pens, combined with a series of circuit-changing wheels, part of which are the units-transmitting wheels and part of which are the tenstransmitting wheels, the said wheels for the units and tens being arranged alternately upon the shaft, substantially as described.

4:. In a signal-trailsmitter, the signal-wheels for units, and the signal-wheels for tens, and the signal-wheels for hundreds, combined with the series of contact-pens and the selectingcylinder having thereon several rows of studs or proj eetion s, some rows comprising one stud, other rows two studs, and other rows three studs, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN C. WILSON.
